' The bifurcations are suflicientlv yielding to Illinois. have inventeda new and useful Improvement in Train-Pipe COU])l1IlgS,'0f wh ch a thefollowing is a specification.

\I v invention relates particularly to means for supporting thecoupling-heads of automatic train-pipe couplings.

My primary object is to provide improved means forholding and centeringcouplingheads in a reliable manner; while permitting all necessaryfreedom of movement thereto to compensate for relative movement of thecars under any working conditions which mav be encountered.

The invention is illustrated in'its preferred embodiment in theaccompanying drawings, in wlnch.

Figure 1 represents a enable the hanger after adjustment on the lug a tobe firmly clamped in place.

, The coupling-head C is provided with the usual guide-prongs c, a passae 0 iii connection with the signal-pipe of the train, a passage c forconnection with the brake-pipe of the'train, and a passage 0 forconnection with the steam-pipe of the train. Projecting rearwardly fromthe central portion of the head is a pi e c, which connects with thepassage 0 0 the coupling-head. and which exten s loosely through anopening c in the s ring-plate b L'pon the pipe c in the rear of thehanger B is a collar 0", equipped with prongs 0 which engage the rearface cf the 1 ring b of the hanger.- The pipe e is probroken side'eleval tional view of a draw-bar of a car with a train-pipecoupling-head supported thereon b v means of my vided with a spline c",which fits in a longitudinal groove c", with which the sleeve c" isprovided internally, the rear end of said groove being closed, asindicated at c". The

improved coupling-head f support: Fig. '2, a section taken as indicatedat line 2 of Fig. 1: Fig. 3, a section taken as 1 indicated at line 3 ofFig. 1; Fig. 4, a section taken as indicated at line I of Fig. 1, thespring for projecting the coupling-head being i removed Fig. of thehanger shown in Fig. 4 with the spring-plate removed from its socket,and

The draw-bar or car-coupling member A provided with a depending boss(l.supplied with horiz: i'itallv-alined slotted openings (1 and withverticallv-serratetl side'surfaces (1' The hanger B comprises a shank band a ring The ring has an opening 11*.

' over which fits the large rear end of the coi ical spring C. hashiiurcations which have vertical serrations on their ad acent surfacesand em- The upper end of the shank?) connection is such that when thepipe c moves rearwardlv, as when two couplingheads are brought togetherin the operation of coupling the cars, the sleeve 1 and the arms carriedthereby, constituting a spider; will move rea-rwardlv with the pipe. TliI't aded onto the rear end of the pi ie c is an elbow c, with which isconnected a llexihle armored hose c", which in practice coiint cted Thetlhow 1: usually occupies a horizontal plane. It is shown rotated to thevertical plane, however. for convenience of illustration. Its front endbears against the sleeve c, affording a stop, when the coupling-head inthe advanced position. 'I he ring 71 of the hanger B is provided on itsrear surface with a lug c, which tapers rearwardlv to a point c. andfits loosel between two'of the arms c of the spider. This lug serves asa guide for the spider and through the medium of the spider maintains hecoupling-head in proper position for cd upling.

It will now be understood that when two cars are brdught together in theoperation of coupling the cars the coupling-heads of the train- )ipeswill engage each other and will be forced inwardly or retracted. In thisaction tlie'spiders will be moved away from the rings 1). somewhat, andthe pipes 0 will be free to swing in any direction to accommodate thecoupling-heads of the train-pipes to anv relative movement of the carswhich may occur under the conditions. of use of the cars upon a railwaytrack.
